CVE-2017-15132 [HIGH] CWE-400 dovecot: Auth leaks memory if SASL authentication is aborted
dovecot: Auth leaks memory if SASL authentication is aborted
A flaw was found in dovecot 2.0 up to 2.2.33 and 2.3.0. An abort of SASL authentication results in a memory leak in dovecot's auth client used by login processes. The leak has impact in high performance configuration where same login processes are reused and can cause the process to crash due to memory exhaustion.
Aborting the process of SASL authentication can lead to a memory leak when the same login processes are reused. An attacker could use this flaw to cause a denial of service due to memory exhaustion.
Mitigation: This issue can be mitigated on vulnerable systems by limiting the login process to a single request per process, which is also the default value.
